To all whom it may concern.-

Be it known that we, PHILIP MUELLER and ANTON (J. SCHUERMANN, citizensof the United States, residing at Decatur, in the county of Macon andState of Illinois, have invented new and useful Improvements inWall-Fittings for Cocks, of which the following is a specification.

This invention relates to an improved wall fitting for cocks, and hasfor an object to provide a fitting wherein a canopy may be used forgiving the fitting a finished and neat appearance, and wherein thecanopy will adjust itself to the angular displacement of the cockrelative to the wall or sink back, so that it will seat about its entireedge against the wall or back.

This invention is a continuation of our application Serial NO. 806,774,filed December 15, 1913.

The canopies generally employed at the present time are screw-threadedto the shank of the faucet, and in order that the canopies may betightened against the wall through which the faucet shank extends thecanopies are provided with angularly disposed wrench-receiving faces bymeans of which the flanges are turned and forced into engagement againstthe wall. It is found that this arrangement and structure isunsatisfactory in that the canopies are marred and disfigured by reasonof the application of wrenches and the like thereto and by reason 'ofthe crushing of the canopies when adjusted to hold the cock or faucetfrom movement.

To overcome these disadvantages is the prime object of this invention,and in carrying out these objects of the invention the improved fittingis provided with a relatively strong collar adjustable upon the shankof'the faucet and adapted to engage the wall so as tofirmly hold thefaucet in place, and to provide a canopy mounted independently of thecollar upon the shank on which it may be adjusted without turning orwithout the application of tools or the like thereto into position tohouse the retaining collar and close the opening in the wall, and thecanopy is of a thin, bendable metal so that it may adjust itself by bodydistortion to the angular position of the faucet relative to the wall orsink back.

In the accompanying drawings-Figure 1 is a vertical sectional viewtakenthrough the improved wall fitting. Fig. 2 is a trans,- verse section onthe line 2-2 of Fig. 1,- showing enlarged the relativepositions of thecanopy and the retaining collar. Fig. 3 is a detail perspective view ofthe retaining collar. Fig. 4 is an edge view of the collar. Fig. 5 is avertical sectional view of a slightly modified form of-fitting. Fig. 6is a transverse section-,taken on the line 6-6 of Fig. 5. Fig. 7 is adetail perspective view of the modified form of retaining collar shownin Fig. 5. Fig. 8 is an edge view of the retaining collar of Fig. 7.Fig. 9 is a vertical sectional view through my improved wall fittingshowing another embodiment thereof. Fig. 10 is a view similar to F g. 9,but showing the position of the parts when the faucet has becomeangularly displaced relative to the wall.

' Referring to these drawings, wherein like characters of referenceindicate similar parts throughout the several views, 10 indicates aservice pipe projecting into an opening 11 in the wall 12 into the endof which pipe is screwed the shank 13 of the faucet 14. The shank 13 isprovided in a usual manner with iron pipe threads for attachment to the(-orres 'umding threads of the service pipe.

(arricd upon. the shank 13 is a. canopy or flange 15 which is formed ofa thin, bend able metal to permit yielding or body distortion withoutcracking or breaking when strain is placed thereon. The canopy isprovided at its outer or smaller end with a cylindrical neck portion ofconsiderable length,

and the end of the neck portion is turned inwardly to provide a flange16. An annular packing ring 17 of rubber or other suitable compressibleand anti-slipping material is received by the neck portion of the canopyand is forced against the inturned flange 1(l'by means of the flangedcollar 18 adapted to fit within the neck portion in the manner shown inthe drawings.- The packing ring is adapted to frictionally engage andbind against the shank, and the ring is of .considerable thickness,being substantially direction, but at the same time the canopyisretained from accidental displacement by jarring or the like; i

Within the canopy 15 is located a retaining collar 19 carried upon theshank 13 and being provided with radial lugs 20 engaging against theouter side of the wall 12 for the purpose of holding the shank firmly inposition when adjusted. This collar 19 is mounted for adjustment uponthe shank 13, and any-suitable means may be employed for holding thecollar upon the shank in adjusted position. In Fig. 1 the means employedfor holding the collar upon the shank comprises a relatively finethreaded portion 21 on the shank immediately adjacent the iron pipethreaded portion which engages in the service pipe. The collar 19 isprovided with internal threads adapted to engage the threads 21 of theshank and not only hold the collar 19 in position when adjusted but alsoprovide means for feeding the collar 19 inwardly against the wall anddrawing out the shank l3 and the end of the service pipe so as to firmlyhold the faucet or cook 14 rigidly 'in place.

From Figs. 2, 3 and 1 it will be particularly noted that the ret.iningcollar 19 is provided with a pluralit of spaced apart radially extendinglugs 20 having preferably flat faces with the inner end of the collar 19and adapted to lie flat against the outer face of the wall or sink back12. By providing these spaced apart rigidly extending lugs a strongcollar is provided which is adapted to span practically any opening andinsure ample support for the flange and prevent. the coupling fromrattling and from distortion. Each of the lugs ,20 is provided with aradial socket or opening 23 adapted for the reception of a spannerwrench, or nail, or some suitable relatively sharp instrument which willcatch in the openings or pockets 23 and turn the entire collar 19. Theadvantage of thus providing for an engagement with the collar in aradial direction, and by means of these relatively thin instruments, isthat the collar 19 may be tightened to the desired degree whereas inprior structures such collars could not be used for the reason that whenthe canopy is pulled forward to expose the collar and its parts the thewall is so small that it will not admit of j the application of a wrenchof proper size to turn the collar.

In assembling the wall fitting shown" in Figs. 1 to 4, the shank 13 isengaged through the opening 11 and with the service pipe 10 in the usualmanner by rotating the faucet and its shank until the desired adjustmentis had between the shank and the service pipe. The canopy 15 is movedoutwardly of the shank 13 from the Wall 12 by'apply- 22 at their. rearside flush spacebetween the canopy and.

ing considerable pressure thereto at diametrically opposite points in adirection paral' lel to the axis or longitudinal center of the shank 13,so that there will be no tendency for the canopy to assume an angularposition relative to the shank which would distort the canopy andprevent slipping. A suitable implement is inserted in the openings ofthe lugs 20, and by means of which the collar 19 is turned upon thethreaded portion 21 of the shank. As the collar approaches the opening11 the lugs 20 bear against the wall 12 and draw the service pipe intothe opening to retain the same from vibration. The canopy 15 is nowmoved inwardly against the wall 12 to close in the collar 19 and itslugs and to cover the opening 11.

Another means for fastening the retaining collar upon the shank and inplace against the wall is shown in Fig. 5 wherein the shank 13 hasnofinely threaded portion but a smooth outer surface over which theretaining collar 19 slides, the latter having also a smooth innersurface. The collar 19 is provided in one side with a point screw 2eextending radially therethrough and adapted for binding engagement atits inner end against the smooth outer surface of the shank 13*. Thisstructure is disclosed to advantage in Figs. 6, and 8. From thesefigures it will be seen that the collar 19 is provided with radiallyextending lugs 20 provided with flat wall engaging faces and beingreinforced by webs or braces 25 projecting from the rear faces of thelugs and extending outward from the body of the collar 19.

If the retaining collar of Figs. 5 to 8 inclusive is employed the sameis. pushed against the wall while the shank 13 is drawn through theopening 11 and when the. de-

.sired tension is had the point screw 24 is is pushed toward the wall tocompletely inclose the collar 19 and its lugs and to cover the opening11.

Referring now to Figs. 9 and 10 wherein is disclosed a slightlydifferent embodiment of my invention, 26 designates a T-coupling forconnecting the sections of the service pipe 10, the T-coupling having aninternally threaded projection to receive the threaded end of the shank13 of the faucet. The collar 19 of this embodiment is in all respectssimilar to that disclosed in Figs. 1 to 4, except that in place of afiat wall engaging face it is'provided with a semi-spherical seat orprojection 27 which is adapted to form a bearing surface which willalways be in contact with substantially the entire edge of the opening11 in the wall 12 and through which the shank of the faucet exfigures,is inclosed or covered by the canopv 15.

When the collar 19 disclosed in Figs. 9

and 10 is used, the faucet shank is secured in place in the threadedprojection of the T-coupling 26 and the collar 19 is rotated to bringthe spherical seat or projection against the edge of the opening 11 inthe wall 12 when upon continued rotation of the collar the T-couplingwill be drawn against the inner surface of the wall. Should the axis ofthe faucet shank not extend at right angles to the outer surface of thewall the collar 19', due t its spherical seat or projection, wouldaccommodate itself to such angular displacement and contact about theentire edge of the opening 11,

while if the collar shown in Figs. 1 to 8 'was used, the collar wouldcontact with or touch the wall 12 at one point only, resulting in athrust upon the threads of the shank which would ultimately cause aloose fit between the collar and the shank.

In Fig. 10 the faucet is shown asangularly displaced relative to thewall 12, and while this showing is somewhat exaggerated for illustrativepurposes, it serves to show the position which the parts assume whensuch angular displacement takes place.

It will be noted that upon angular displacement of the faucet relativeto the wall the canopy will adjust itself by body distortion, as it isconstructed of a thin, bendable metal, to such angular displacement, andthe canopy will contact about its entire edge against the wall and thusthe collar and shank is entirely inclosed and all open spaces betweenthe canopy and the wall in which dirt or the like may accumulate areeliminated. The collar is adapted to be adjusted longitudinally of theshank by applying pressure thereto in the proper direction, but uponapplying pressure to one side of the canopy only, the canopy tends tobecome angularly displaced relative to the shank, and due to theanti-slipping characteristic of the packing and the extended bearingbetween the canopy and the shank slipping of the canopy is preventedwith the result that the canopy becomes bodily distorted to adjustitself to such strains as may be placed upon it. The shank of the faucetor cock may become angularly displaced relative to the face of the wallor sink back after the parts have been assembled due to relativemovement of the service pipe to the wall, or should the threads on theshank of the faucet not be turned from the true center of the cock, orshould the screw threads of the T shown in Figs. 9 and 10 not be tappedstraight, the shank would incline slightly at an angle to the outersurface of the 'wall 12-.

' from vibration and in place is taken from canopy will not be marred sothat at all times a neat and finished fitting is had.

In present types of adjustable screw flanges, screwed upon a faucetshank, generally a sleeve projects over the screwthreaded part of theshank andthe space intervening between the faucet shank and flangesleeve becomes filled with dirt. This is unsanitary as it is impossibleto clean this flange sleeve. Again, the fitting of this invention ismore sanitary than ordinary fittings since the canopy has noangularlydisposed faces, about the corners of which may collect dirt andthe like, but presents an uninterrupted rounded surface having notendencies to collect dust and dirt and which may be easily cleaned.
